Stacked orders force drivers to deliver lukewarm food to the second customer

Delivery apps batch two or three orders from different restaurants into a single driver trip to reduce costs, but the second or third customer's food sits in the car for 20-40 extra minutes while earlier stops are completed. The second customer receives cold fries and congealed sauce, blames the restaurant, leaves a 1-star review, and the restaurant's rating drops for something entirely outside their control. Platforms keep stacking orders because paying one driver for two deliveries is dramatically cheaper than dispatching two drivers, and the cost of the occasional bad review is externalized onto the restaurant rather than absorbed by the platform.
